My datsun maxima keeps stalling out weather im in

Without more information... The RPM slows down when it is put in gear. Try applying brake and some gas pedal to keep rpm up some and see if it still stalls. If it keeps running maybe the idle speed is too low or a spark plug fouling

Tune up, clean the throttle body.

IGNITION TIMING

1983 Nissan/Datsun 2.8L FI 6cyl

The Ignition Timing

Application:
With automatic transmission


8 Degrees,Before top dead center*Set at warm idle speed (650 RPM)*Distributor vacuum hose disconnected & plugged*Transmission in drive (parking brake engaged)

If it stalls when the brake lights come on then the idle is too slow. The high amps of the lights will load down the engine and lowers the idle.

Sometimes that's caused by a vacuum leak near the manifold area.

Sometimes air in the coolant will cause an idle problem. Air will keep the air temp sensor from sending proper info.
Hope this helps.

check that the brake booster is not leaking vacuum when you have your foot on the brakes and upsetting the air /fuel mixture at idle. When coming to a stop use the hand brake to stop the car and if it keeps idling ok then it will be the booster.

It uses an electric pump inside the gas tank.

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

your idle

i think your exhaust might have a leak which is heating up your oil when this happens the engine suffocates and wants to die.

is it possible that the idle speed is set to low?
